So, the group ends up in the Xyz Dimension….because of a dimensional transport glitch.

Unknown at this point if its all the Lancers or only Yuya, Gongenzaka and Sawartari, which another preview specifically mentioned.

They find Kite there taking on Obelisk Force.

The new OP, Light of Hope, is being sung by a group calling themselves “Unknown Number”. The single will be released on May 25th, while the single for the ED, Vision will be out April 27th.
